我尝试了什么：



它正在工作，现在它不再是我不知道该尝试什么

解决方案

在Windows窗体中，透明不是。所有这一切都是告诉控件采用包含它的容器的前/后地面属性。



例如，你将一个面板放在一个表格上。如果将Panel的BackColor设置为Transparent，Panel将采用Form的BackColor属性。它不会使面板透明。



有一些文章和论坛的答案会带你通过不绘制来制作你自己的伪透明面板控件小组的背景。这种技巧可能会或可能不会为你做，这取决于你的Panel控件背后的表格上发生了什么。

解决方案

In Windows Forms, Transparent isn't. All that does is tell the control to take on the fore/back ground properties of the container that contains it.

For example, you put a Panel on a Form. If you set the BackColor of the Panel to Transparent, the Panel will take on the BackColor property of the Form. It does NOT make the Panel see-through.

There are some articles and forum answers out there that take you through making your own pseudo-transparent Panel control by not drawing the background of the Panel. This technique may or may not do the trick for you, depending on what's going on on your Form behind your Panel control.
